    • An FMCW radar device executes a frequency analysis for a beat signal in a frequency increase interval and a frequency decrease interval, to obtain frequency components in a predetermined high frequency range exceeding a frequency range corresponding to a target detection frequency range within which a target object for detection should be detected. Then the FMCW radar device calculates a value related to a sum of intensities of frequency components within the high frequency range respectively for each of the frequency increase interval and the frequency decrease interval. In the case that one of the calculated integrals is larger than a threshold, the FMCW radar device determines that the FMCW radar device is interfered with by a nearby radar device.

    • Occurrence of interference is detected using sampled amplitude data obtained by oversampling a beat signal. It is detected by comparing the absolute value (|VD|) of variation in the sampled data with a threshold value (TH). When interference occurs, a wideband signal is superposed on the beat signal, and this disturbs the signal waveform of the beat signal to drastically varies its amplitude. Therefore, occurrence of interference can be detected without fail regardless of the scheme on which a radar as the source of an interference wave is based and even when the amplitude of the interference wave is low. In addition, when low-frequency noise is superposed on the beat signal, erroneous detection of occurrence of interference can be prevented.
    • 使用通过过采样拍频信号获得的采样振幅数据来检测干扰的发生。 通过将采样数据的变化的绝对值(| VD |)与阈值(TH)进行比较来检测。 当发生干扰时,宽带信号叠加在节拍信号上,这样会扰乱拍频信号的信号波形,从而大大改变其幅度。 因此,即使干扰波的幅度低,雷达作为干扰波的来源,即使是干扰波源也是可以的,所以能够毫无疑问地检测出干扰的发生。 此外,当低频噪声叠加在节拍信号上时,可以防止发生干扰的错误检测。
